We expect dramatic temperature contrasts across the state again with the approaching storm. High temperatures will range from the 30s and 40s over northeastern Colorado, to the 70s south of the Arkansas River. The cold front will race southward this afternoon, probably reaching Colorado Springs early this afternoon, then racing southward to the New Mexico state line by early this evening. The wind will be strong on either side of the cold front, and could be gusting over 40 mph at times. The difference will be that the wind ahead of the front will at least be a relatively warm, westerly wind, once that cold front passes the wind will be very cold and out of the north or northeast.
Futurecast is suggesting areas of snow will be moving over northern areas this evening. The snow may not be terribly heavy initially, but the temperature change will be dramatic.
Winter Weather Advisories have been issued by the National Weather Service Forecast Offices around the region for the areas shaded in white, and a Winter Storm Warning is up for the mountains west of Denver where you see red. A combination of wind, snow and quickly falling temperatures should lead to poor visibility at times, and cause roadways to become icy and/or snow packed in these areas starting late today and lasting into Tuesday morning.
Total snowfall accumulations won't be terribly impressive with this storm, but in the pink shaded areas as much as 2" to 5" of snow could fall. In general we think these amounts will be pretty common over the Palmer Divide near the mountains, and for much of northern Teller county too. In the dark pink areas as much as 4" to 8" could fall, especially if we can keep some snow falling into Tuesday morning. Amounts like this are most likely in pockets near the Wet and Sangre De Cristo mountains as well as along the Continental Divide. In the white shaded areas, including Colorado Springs proper and areas out along US 24 towards Limon, we expect 1" to 3", mostly on the grass but some slick roadways are certainly possible overnight. Accumulations like this are also possible into Fremont county, including Canon City. For lower elevations we do believe it will snow tonight, but much of the snow will melt on the relatively warm roadways. Still, some minor accumulations of snow are possible on cooler surfaces, especially north of the Arkansas River.
